Just installed dual stage manual electric boost controller in my 2004 v70 2.5t awd,i own a few volvos,but never tinkerd with em,,was very skeptical about doing this cause i heard the new engines did not like this,i think thats bs,it all works well ..yeah i had to clear the engine lite a few times till i got it set up rite on boyh stages..i have the first stage set at 10psi,and the second stage set at 15psi,,,,my factory was only about 6 or seven pounds in first and second and a few pounds in 3,4,and 5,,i must say even the first stage with 1o psi is very cool and responsive all the time,,holds 10 thru all the gears,and as for second stage yee haa..i also have 2004 s60 t5,and my v70 now blows the doors off it,,i recomend this install to everybody with these cars...feel free to post a response or question as i am new here and would like to get more info on a few other things..
